"2 .You're mixing video decoding with audio decoding"
Sorry, I did not write it properly, I just wanted to say that strangely some avis with ac3 plays quiet and others with the same audio codec plays loud. This is where I get the feeling that mpeg4-part2 might caused the quiet sound. Since you wrote that ac3 is passed through untouched I understand it must be something else.

 

Thank you for making that higher volume issue clear, so it's manufacturer's driver causing it, not OpenPli. Damn it. I'll have to switch from using Xtrend's volume control to TV volume control then. :(

Videos play with almost exact audio level in VLC (on a Windows PC and an Andriod tablet) but not on OpenPli images. I can't tell if this issue is only on MastaG's images or on OpenPli in general. I haven't noticed the difference on a very old OpenPli image, probably 10 months old. But I don't have that old image anymore so I can't flash it back to tell the difference between an old OpenPli image, the latest OpenPli image and MastaG's image. But I'm going to compare the latest OpenPli and MastaG at least. (But isn't MastaG's image based on some of the latest OpenPli images?)

I believe that the main issue is that newer OpenPli images have much stronger audio level output on DVB channels (this applies to mpeg audio, ac3 audio and aac audio too) than previous versions of OpenPli. So maybe this difference is caused by fact, that some video files are decoded using mpeg4-part2 and this produces normal sound but other video playback uses built-in (original) video decoding components which produces the same audio level as DVB decoding (which means much louder that before). I'm going to compare the latest OpenPli with Masta's image and share my findings.

Maybe this can be solved easily if it is possible to adjust somehow (internaly) the audio level decoding of new OpenPli images (and I don't mean VOL+/- buttons on the remote control).

Masta, I think the problem with different audio volume has something to do with last few OpenPli images. I've noticed that since approx. February dvb streams are much louder than they used to be in previous images. So maybe your image doesn't provide low audio output, it's OpenPli's dvb decoding provide much louder audio than before. Just guessing here.
Another strange thing is that videos with audio ac-3 5.1 provide normal audio level but others very quiet. I'd understand it if this is for mpeg audio vs ac-3 audio, but one ac-3 5.1 is normal/loud while other ac-3 with 5.1 is very quiet. (On a PC or BD player it's always the same for every ac-3 audio).

Hi MastaG, thank you for your image, I've struggled with choppy video playback on avi files for ages and now it's gone and videos play smoothly!

Just one little issue on my Xtrend ET7000, some videos have quiet sound comparing to others. I thought it's the audio codec but it's not. Some audio tracks in MP3 or AC3 format plays normaly, others play very quiet. It's annoying when you switch back to TV boradcast, which has audio level quite high, comparing to those videos with quiet sound. I alway have to adjust the volume from 100% to 10%. Can I adjust this difference somehow? It could be a config file, I don't need graphics options for this.

Anyway, great job!

So, good news, this image plays avi videos just fine. But with one little problem, some videos have quiet sound comparing to others. I thought it's the audio codec but it's not. Some audio tracks in MP3 or AC3 format plays normaly, others play quiet. But videos now play fluently, which is excelent!
